Phone in your pocket, in a meeting, or on vibrate all day? With Avibrim you can tell who is calling or texting just by how your phone vibrates.

Give Mom a heartbeat, your boss an SOS and your best friend a rhythm you tapped out yourself. When they call or message you, you feel it and you know, without taking your phone out.

★ HOW IT WORKS
• Pick a contact or a whole group and choose their pattern
• Feel each pattern before you choose it
• When they call, Avibrim plays their pattern
• Everyone else gets a basic buzz, or no vibration at all, your choice

★ FEEL WHO'S TEXTING, TOO
• Their pattern also plays when they message you on WhatsApp, Telegram, Signal, Messenger, Viber or SMS
• Muted chats and Do Not Disturb are respected
• Only the sender is used to pick the pattern. Your messages are never used, saved or uploaded

★ MAKE YOUR OWN PATTERNS
• Tap or hold the circle to record a rhythm
• Touch higher on the circle for a stronger vibration (on supported phones)
• Fine-tune every pulse: drag it sideways for its length, up or down for its strength
• Turn a word into Morse code: MOM, SOS or your own name
• 10 built-in patterns to start, including Heartbeat, Pulse, Swell, Ripple, SOS and Bee

★ NEVER MISS THE CALL THAT MATTERS
• Patterns for contact groups like Family or Work, and one for all your Favorites
• Repeat until you answer, or a set number of times
• Get stronger with each repeat, from gentle to full strength
• Missed-call reminder: a minute later, their pattern plays once more
• Repeat callers get through: a second call within 3 minutes plays at full strength, even in quiet hours
• Vibrate on silent for the people who matter
• Starred contacts can still vibrate during Do Not Disturb
• Quiet hours: pause Avibrim every night

★ SHARE AND KEEP YOUR PATTERNS
• Share a pattern by QR code: a friend scans it and has it too
• Back up all patterns and assignments to a file for your next phone

★ BUILT FOR EVERY DAY
• Works in the background, even when the app is closed
• Pause for an hour from Quick Settings; Avibrim turns back on by itself
• Light and dark mode
• A short setup guide on first launch
• In English, Spanish, German, Russian and Chinese

★ PRIVATE BY DESIGN
• Your contacts, callers' numbers and messages never leave your phone
• No ads
• Avibrim never blocks or rejects calls

★ SETUP TIPS
• On Android 10 and newer, Avibrim asks to be your "caller ID & spam app". This is how Android tells it who is calling. Avibrim only uses the number to pick the right vibration.
• Turn off your phone's own call vibration ("Vibrate for calls" or "Ring vibration") so it doesn't cover your patterns. The setup guide shows you where.
• Vibration strength needs a phone whose vibration motor can vary strength. Avibrim shows whether yours can in Settings.
• Message vibrations need notification access. Turn off the messaging app's own vibration so you feel only the pattern.

Feel who's calling.
